CentOS is suitable for enterprise and server environments due to its stability and long life cycle. 1.CentOS provides up to 10 years of support, suitable for scenarios that require stable operation. 2.Ubuntu is suitable for environments that require quick updates and user-friendly. 3.Debian is suitable for developers who need pure and free software. 4.Fedora is suitable for users who like to try the latest technologies.

Alternatives to CentOS include AlmaLinux, RockyLinux, and OracleLinux. 1.AlmaLinux and RockyLinux rebuild RHEL 1:1, providing high stability and compatibility, suitable for enterprise environments. 2. OracleLinux provides high performance through UEK, suitable for users who are familiar with the Oracle technology stack. 3. When choosing, stability, community support and package management should be considered.

CentOS alternatives include RockyLinux, AlmaLinux, and OracleLinux. 1. RockyLinux and AlmaLinux provide stable distributions compatible with RHEL, suitable for users who need long-term support. 2. CentOSStream is suitable for users who focus on new features and development cycles. 3. OracleLinux is suitable for users who need enterprise-level support.

CentOS needs alternatives because CentOSStream no longer provides long-term support. Alternative options include: 1. RockyLinux, which provides 10 years of life cycle support, suitable for users who need stability. 2.AlmaLinux also provides 10 years of support and has strong community support. 3. OracleLinux, provides RHEL-compatible version, and flexible life cycle management.

The end of CentOS has had a significant impact on users, with users having the option of RHEL, AlmaLinux, Debian or Ubuntu as alternatives. 1. The migration cost is high, requiring time and money. 2. Community division affects open source projects. 3.RHEL provides commercial support, but it is costly. 4.AlmaLinux is similar to CentOS and has low migration costs. 5. Debian and Ubuntu need more time to adapt.

CentOS is suitable as an enterprise-class server operating system because it is stable, secure and free. 1) It is based on RHEL and provides high compatibility with RHEL. 2) Use yum for package management to ensure that the software is easy to install and update. 3) The community regularly releases security patches, with a support cycle of up to 10 years.

The reason why CentOS stopped maintaining is RedHat's strategic change. User response strategies include: 1. Migrating to other distributions, such as UbuntuServer, Debian or RockyLinux; 2. Continue to use CentOS7 until June 2024; 3. Turning to CentOSStream; 4. Build solutions, such as custom distributions based on RHEL or using container technology.
